COVER INFORMATION Station: VLBA_NL (Code Nl ) Experiment: Follow-up Imaging of Three NGC4258-like Water Megamasers Exp. Code: BK114D Schedule Version: 2.00 Processed by SCHED version: 6.01 Release: Late March 2005 PI: Paul T. Kondratko Address: Harvard-Smithsonian CfA, MS 10 60 Garden Street Cambridge, MA 02138 USA Phone: 617 497 6996 EMAIL: pkondrat@cfa.harvard.edu Fax: 617 495 7345 Phone during observation: 617 851 3887 Observing mode: 256-4-2 1.3 cm Notes: 10 min setup time. Pointing calibration at the GBT and at EB is crucial and is scheduled every ~1.5 hours. VLA: extend phasing scans on 0821+394 if necessary to obtain reasonable RMS. VLA scan on 3C147 is critical.
